An ear-insertable protecting device includes a body unit and an integral extending tubular portion adapted to be received in the aperture of the auditory meatus of the ear so it affects a sound seal between the inserted portion and the ear canal with the device having an auditory channel extending therethrough with sound attenuating means located in the auditory channel, includes a cooperating retaining device having a barb at each end which can be plugged into the body unit, in either the auditory channel or another opening provided therefor whereby the device can provide partial or total sound occlusion at the option of the user. In addition, the tubular portion is preferably tapered from the body unit and has a radially extending web wound spirally thereon to facilitate affecting a sound seal with the ear canal without accompanying discomfort. Further, the barb may include a lanyard to prevent loss of the device.
